There is no filter. The egr valve would be located on the intake manifold. A pipe from the exhaust stream will connect to it. When the valve is opened by a vacuum signal, exhaust gases will be drawn into the intake manifold, and then into the cylinders. It's a pollution control system to lower combustion temperatures so certain oxides are not produced and emitted out the exhaust pipe.
